Package : pdns-recursor
Vulnerability : design flaw
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2008-1637
Amit Klein discovered that pdns-recursor, a caching DNS resolver, uses a
weak random number generator to create DNS transaction IDs and UDP
source port numbers. As a result, cache poisoning attacks were
simplified. (CVE-2008-1637)
For the stable distribution (etch), these problems have been fixed in
version 3.1.4-1+etch1.
For the unstable distribution (sid), these problems have been fixed in
version 3.1.5-1.
We recommend that you upgrade your pdns-recursor package.
